Rotary brush



Patent-ed Nov. 10, '1925.

UNITED STATES RUDOLPH R. RAIDINSE, OF CLEVELAND, OHIO.

ROTARY BRUSH.

Application filed April 14, 1924. Serial No. 706,833.

To all whom 'it may Gomera:

Be it known that I, RUDoLPH R. RADINSE, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Rotary Brushes, of whichthe following is a specification.

This invention relates to rotary brushes and is an improvement upon theconstruction disclosed in my Patents Numbered 988,- 506 and 1,32t`,372,granted April 4, 1911 and December 80, 1919.

In these patents the construction of the bristle holders or carriers issuch as results in relative displacement thereof upon assembling anumber vof these holders and securing them together with clampingmembers which obviously are pressed against the opposite sides of thecentral plates and are arranged upon a shaft. Furthermore the structureemployed in brushes made in' accordance with these patents must besupplied in numbers and have yvarious sized shaft openings andconsequently the cost to the user is unnecessarily great.

It is the primary object of this improvement to eliminate the abovefaults and provide means for rigidly holding` the several bristleholders in proper relative positions and to provide an opening in whichmay be arranged adapters whereby one brush may be mounted upon shafts orspindles of different diameters.

Other objects will be in part obvious and in part pointed outhereinafter.

In order that the invention and its mode of operation may be readilyunderstood by persons skilled in the art, I have in theaccompanyingillustrative drawings and in the following detaileddescription based thereon set out one possible embodiment of the same.

In these drawings:

Fig. 1 is a side elevation of the completed brush with the adapterarranged therein;

Fig. 2 is a sectional view of the brush with the adapter removedtherefrom;

Fig. 8 is a detailed plan view of one of the bristle carriers prior tohaving the bristles clainped therein;

Fig. t is a sectional view showing the tongues between which thebristles are clamped and the spacing fingers;

Having more particular reference to the drawings throughout whichsimilar characters of reference designate similar parts,

this rotary brush may be stated as comprising a set of individualbristle holders or carriers 10, each identically formed and adapted tobe clamped together to form the complete brush.

Each bristle holder or carrier 10 comprises a flat metal ring which isslit radially from its periphery to a point substantially mid-way thewidth of said ring, thereby forming tongues 11, which are alternatelystamped in opposite directions. .Between these oppositely stampedtongues is arranged a twisted Wire ring 12 in the twists of which arepositioned the bristles 13 of wire or other preferred material. As afurther means for efi'ectively retaining these bristle carrying ringsbetween the said tongues I arrange upon opposite sides of the twistedring and beneath the tongues a pair of flat metal bands 14: which aretightly engaged with the bristles through compressing said tongues. Incthis manner the bristles are securely retained in position and may bereadily replaced through bending the tongues outwardly and removing thetwisted ring.

The inner portion 15 of each ring forming the body of the bristle holderis bent laterally into the plane of one of the circular rows of tonguesand has its inner edge provided with V-shaped notches 16' to formspacing fingers 18, these fingers being bent axially with their edgeslying in the plane of the other row of tongues. Recesses 16 are providedon the inner periphery of the portion 15 at the apices of the notches16' and communicate therewith. These recesses 16 are designed to seatlengths of wire 17 or the like by means of which the several bristleholders are clamped together. The spacing fingers 18 retain the severalholders against undue displacement when they are clamped together.

It is obvious that no reasonable amount of pressure upon the oppositesides of the assembled brush will cause any relative movement betweenthe several bristle carriers. As illustrated in the accompanyingdrawings, the spacing members or fingers 18 of each bristle holder 10contact with the corresponding members of the adjacent holder and thusretain said holder as just stated.

The opening 19 resulting from the formation of these spacing fingers 18is of such size as to readily accommodate any of the .standardsized'fshaftsor spindlesand istalso designed to receive an adapter (notshown) by means of which the brush may be securely clamped to a shaft'iManifestly certain changes in the details of construction may beresorted to as will fall within the scopeof'` the. appendecl claims andsuch changes I consider within the spirit of my inventiomv I: claim:
